vApplication filed April 21, 1920. Serial No. 375,517..

To all whom t may concern:

Be it 4known that I, ALBERT R. li'Ls'rnA, a citizen'oic the United States, residing;- at

South Holland, in the county of Cooky andof tiactor in which the operator usually.

walks in back guidingthe machine and con-v trolling the apparatus propelled thereto. be employed upon any type of tractor or vehicle to which the same may be applicable. The invention has amongA its objects' the production ot' a device` ot the kind described, thatis simple, compact, convenient, eliicient, .reliable `and satistactory for use wherever found applicable. The same has particularly as van objectthe production of a device ofthe kind described which may be easily and quickly controlled whereby injury to the plants being cultivatedmay be avoided. Many other objects and advantages-of the construction kherein shown and described will be obvious -to those skilledl in the art from the disclosure herein given. y

Tothis end my invention consists in the novel construction, arrangement `and com-l bination of parts herein shown and described, and more particularlypointed. out inthe claims. i y

In the drawings, wherein like reference characters indicate like or corresponding parts, j'

Figure 1 is a sidev elevation of my improved attachment applied' for. use on a tractor v; Figure 2 is a plan view ot the same; Figure 3 is a sectional view takensubstantially on line 3-3 ot Figure 2;l

Figure 4 is a sectional view taken substantially on line Lile-dot Figure 3; and

Figure 5 is a sectional view taken substantially on line 5-5 of lFigure 3. f

Referringto the drawings,y in order that the application ot my device may be clear, I have shown the same attached to a form of tractor having one or more wheels 2,y carrying a trame 1, 3 being a gas-engine or other source of power. In the machine shown, 4 represents a` gasoline-tank or the like, 5 a water-tank orthe like, 6 the :iiywheel of the engine, it being understood that the engine is operatively -connected with the driving wheels 2 in any suitable manner, mechanism is controlled as desired.y As

shown, 1 provide frame bars 7-7,` which' tractor trame 1 in rlhe frame handlemay be attached to the any suitable manner.

,raar-iss and that the tractor `'driving bars 8-8 are preferably adjustably secured to the trame bars 7-7 and afford a means ot manipulating the tractor-when desired, and also a support for myiinprovedfcontrollingmechanism, which is adapted to'nottor, .but also control ythe -travel or movement of .the culti'vators, as will bek hereinafter described.. By adjustably securing the bar 12. The bar 12 is provided withmeans Shan ineilonly steer or control the travel of the tracfor connecting the shovels, plows or the like,

of the cultivatorthereto, it being yunderstood that theyk may be attached thereto inr any desired manner, and thaty the bar may be ot sufficient-length to carryany desired number of cultivator plows'. vide a U shapedinember consisting of the legs 14 connected by the part, 15, which. is secured to the bar 12 betweenthe frame bars 7--7, by bolts 16 or thefequivalent. l

As shown, I proalso secure the members consisting of the depending portions 17 and the extending portionl, which are securedto` the bar yby bolts 19, or ktheir equivalents, The legs le and dependingbars 17 carry a U shaped ltrame ateachside, consisting ot the legs 2() l and connecting portions 21, the same being secured to thefpa'rts 14 and-17 in any suitable manner. es showml secure the parts together by means of bolts 22, it lbeing understood that there may be any desired number ot additional holes so as to lprovide' di'ferent adjustments. Each of the members .20-21e- 2O carries the desired shaped shovels, plows,

ror cultivators, which may be attached thereto iio in any suitable manner. As shown', I pro- Vide brackets or memberst to which are scoured the shovels of the desired type. l have shown the shovels 25 secured to the brackets 2st by bolts 26 so that they may be adjusted as required. have shown the brackets secured to the U shaped part ot' the extending portions by bolts 27 and nuts 28. It will be noted by referring to Figures 3 and -1 that lf preferably slot the U shaped parts as indicated at 29, so that the shovels may be adjusted laterally, as may be iifounil necessary. Obviously as the bar l2 is shitt-ed lengthwise the shovels carried ti-iereby will likewise be shifted. The bar may be provided with any suitable actuating mechanism preferred so that it may be operated trom adjai'ent the lree end oi' the handles. is shown, .l provide a shait 33, having a handle 32, the shatt extending 'through the fitting or bearing member 3ft-. Secured to shaft is a gear 35 arranged tocooperate with a rack bar 36 mounted on and secured to the bar l2. l preter to support the cnil uit the shaft adjacent the gear 35, and ttor this purpose l provide a bracket member con-- sisting ot thecross bars having depending legs 38 arranged tor attaclnzient lo the bars T. This member may be braced by the brace members 39, as indicated in Figure 2.' l have illustrated in Figure l, a brace rod `.onsisting oi the parts 30 and 3l, vhich are connected to the `trames 20-21-20 and to the tractor traine l, or the equivalent.

Tt is believed that the operation oi the dcvice will be clear from the preceding description and drawings. Assuming that the tractor is moving along its path, the operator walking behind steers the same by means ot a handle-bar 32 in the same manner as he would by the Ahandle-bars S. Tn case the machine does not run entirely straight,-or that it sheets olf to one side, or the plant is out of alignment with the other plants, the operator by manipulating the handles 3Q, and partially rotating shaft 33 may quickly shift the bar l2 and the cultivators connected therewith, so as to avoid injuring the plants. This can be done much quicker than would be possible to throw the machine. In addition, drawing the handles 8 8 to one side without independently controlling the cultivators may have a tendency to throw the cultivator blades too far the other way. With my improved attachn'ient, the operator may throw the handles to turn the machine and at the same time turn the sliatt to control the cultivat-ors and move tnem in the opposite directions just the desired distante to avoid injury to the plants. The operator is thereby enabled to turn the machine ,vithout stopping it or slowing up, andat the same time without removing his hands to control the cultivators and maintain them in their proper line of travel. The device is exceedingly simple and there is nothing to get out ol" order or require constant adjustment. The same is applicable tor use on practically any type ot tractor, particularly the types similar to that illustrated and described, and may be constructed to cultivate one or more rows. The device, not only prevents injury to the crop, but likewise is a time saver as it is not necessary to slow down or stop the machine in order to turn it should the same veer to one side. 1

Having thus described my invention it is obvious that innnaterial niodiiicationsmay be made in the saine without departing i'rom the spirit oi my invention; hence l do not wish to be understood as limiting niysell to the exact l'orin, arrangement, construction and combination ot parts herein shown and described or uses mentioned.

lVhat l claim as new and desire to secure by Letters Patent is:

l. ln a device oit the kind described and in combination, a cultivator trame adapted `to be connected to the rear ot a driving means and having a pair otregistering slots therethrough in a horizontal plane, a bar slidable through said slots in a straight line trans.'erseiy 'et' the direction ot travel ot said driving means, cultivator mechanism suspended l'rom said bar, means for adjusting said mechanism vertically of said bar, a rock shaft extending' rearwardly and upwardly oit said bar, a controlling handle at the rear end of said shaft and a gear at the torward end thereof, and a rack on said bar between the slotted sides ot the trame, said rack meshing with said gear and being limited at the ends its movement .in both directions by abutting against said sides of the trame. y

In a device ot the kind described and in combination, a cultivator trame adapted to be connected to the rear ol a driving means and having a pair of registering slots therethrough in a horizontal plane, a bar slidable through said slots in a straight line transversely oi the direction oit the travel ot said; driving means, cultivator mechanism suspended from said bar, means for adjusting said bar, and means for actuating said bar comprising a shaft arranged transversely thereoi, a lcontrolling handle at the end ot the shaft, a gear at the torward end ot the shaft, and a rack on said bar to mesh with said gear, said"i'ac`k adapted to abut against the sides of the Atrame to limit its movement .in both directions.

Tn testimony whereof, T have hereunto signed my name in the presence of two subscribing witnesses.
